ANCHOBRSOCKET.

Specification of Letters Patent.

Patented June a into.

Application filed June 7, 1909. Serial No. 500,727.

To all whom 'it may concern:

Be it known that I, IRVING CowLEs, citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Anchor-Sockets; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to a novel construction in a device adapted to beembedded in concrete or similar material, which is molded in plasticform and subsequently sets, for the purpose of providing sockets thereinfor the anchorage of fixtures of all kinds, the object bein to provide asimple and efiicient device of this character and consists in thefeatures of construction and combination of parts hereinafter fullydescribed and claimed.

In the accompanying drawings illustrating this invention: Figure l-' 18a vertical transverse section of a device constructed in accordance withmy invention showing the same embedded .in a concrete ceiling and havinga bolt secured therein. Fig.'2- is a top plan view of the device. Fig. 3is a, plan section of the same on the line 3-3 of Fig. --1. spcctiveView of one of the two members constituting my device.

My invention'has for its object to provide a device for anchoringfixtures to concrete walls, ceilings, floors and the like, which ischeap, easily a plied and which furthermore will permit 0 the easyinsertion of a lint adapted to receive the shank of a bolt and permitlateral play in one direction of said bolt in order to line up pipes,line shafting and the like, and which furthermore permits of theadmission of a considerable length of shank of a bolt so as to enablethe elevation of fixtures to be varied and adjusted to a considerableextent.

My said device comprises two identical members A preferably of cast ironor other suitable metal, said members A being each provided on theirupper ends adjacent their op osed faces with male and female interlocting devices B and C respectively, which when said members are opposed,oppose each other. The member B consists of a hook which is adapted toenter a slot in the member C when said members A are disposed at anangle of about ninety degrees to each Fig. -+lis a detail per-- other,and which when said members are turned parallel with each other so thattheir opposing faces contact with each other, to engage at its free endthe rear face of the member C thus holding said members A againstrelative movement in all directions except pivotally. Each of saidmembers A is substantially rectangular in vertical longitudinal sectionand is provided with paral e1 side walls D and a top wall E dis osedperpendicularly to said side walls and on which said male and femaleinterlocking members B and G are disposed. Said top wall E terminates atone end in a free flan e F.

T e rear wall G of each member A is perpendicular to the side walls Dand top.

wall E and between its ends is deflected inwardly on an incline as at Hand terminates at its u per end in an olf-set portion I which is paralel with the portion G thereof, sa d portion I serving to contract thespace be tween said rear wall and'the meeting edges of the side and topwallsof the device. At its lower end said rear wall G is provided with aflange J extending the entire length thereof and at its ends joining theside walls D, the space between opposing flanges when said members A areassembled as shown in Figs. -1, -2 and 3- constituting a longitudinalslot through which the shank K of the bolt or other threaded member isadapted to pass, the upper walls of said flanges J constitutingshoulders upon which the nut L engaging the shank K of the bolt isadapted to rest. The rear wall G of each member A is further providedbetween its lower end and the deflected portion H thereof with a. rib Mwhich extends from one end of the wall D to a oint midway between theends of said wall lel with said flange J. On the outer face of said wallG and or. the. bottom edge thereof I provide a plurality (if-projectionsN G, paral each of which is provided in its free end with a recess 0through which the shank of a mad or the like is adapted to pass, saidnail or other fastening device. serving to securethe members A upon thebottom of the mold in which the concrete embedding said device 18received and the permanent posltion of the device in the wall, ceilingor the formed between said flan s J until it is completely contained int e hollow space within the device and is then turned until it hasassumed a horizontal position and rests must be moved to one end portionof the slot so that the inserted edge will avoid contact with one ofsaid ribs M and any hindrance to its insertion and positioning thusproshank K therewit ment the said nut may obviously be moved vided.After its insertion and positioning the said nut L may be movedlongitudinal}? ofthe device to a point substantially mi way between theends thereof and the threaded member K then inserted and engagedtherewith. The said ribs M, when the nut is so positioned, limit theupward movement of the same thus rendering easy the operation of onaging the said threaded After such engagelongitudinally'in eitherdirection and positioned as desired to bring pipe or other.

fixtures suspended or anchored thereby into alinement.

I am aware that inserts having some fea tures of construction in commonwith m de vice are in use and that the I'BCOI'dSuO the Patent Oflicedisclose other patented devices which have some features incommon withmy invention, the latter being distinguished from the prior art so faras I am -acquainted therewith in the following features of construction,namely: 3

First: My said insert being made in two parts cast from a common atternand in terlockedavoids the necesslt of the employment of cores incasting t e same without minimizing the strength thereof thus greatlyreducin the cost of the casting.

Second: My evice permits of longitudinal adjustment of the bolt or otherdevice without reducing the seatin surface of the nut on the flanges Jthereo Third: The depth of the hollow space within the device enablesthe-shank to be inserted for a distance sufficient for all uroses ofadjustment and is of such a width in comparison with the diameter of thebolt so as to. allow lateral play for said shank this being essentialespecially when the device is employed to anchor heating pipes, or thelike, of great length and which therefore, will expand and contract to avery considerable extent under the relativel great variation intemperature to which' they are subjected.

Fourth: By means of the ribs M all diiiiculty in engaging the nut withthe bolt after insertion of the former is obviated thus rendering thedevice more eiiicient than.

It is of course, necessary that the device be made of difierent sizes.to receive and enage nuts of various standard sizes, and? partin fiomthe invention as defined in the appen ed claims.

1. An anchor socket of the kind specifi comprising two equal opposed,members each provided on one edge with a slot,-a hook on said edge ofeach member opposing and en tering'theslot of the; other whereb mem ers.are engaged and interlocks with each other, said opposed members whenas= sembled constituting a hollow body, paral lel flanges on opposedwalls of said members between which a slot is formed when said membersare assembled, said flanges constituting supports for a nut the slottedwall of said socket being exposed when'the same is embedded.

2. anchor socket for concrete walls comprising two equal opposed memberseach rovided on one ed s with a male and a emale interlocking evicerespwtively, each of said respective devices opposing and engaging theother of the o posed member, said members when assemb edconstituting ahollow body adapted to be embedded in the concrete, one wall thereofbein exposed and provided with a longitudinal s 0t, shoulders saidordering said slot and ada' ted to support a sai shouldersa distancesubstantially equal to the thickness of the supported nut.
